The combination of national media, groups not affiliated with the debate voicing their concerns outside the venue, candidates and related security details, in addition to normal rush hour traffic may cause significant delays on Broadway, US 36 and around later in the day, a Boulder City spokesperson said.

The spokesperson recommended drivers use alternate routes to get from place to place or have a set time to do what you need to do to avoid the traffic headache.

"Rolling road closures and traffic delays are expected on Broadway between Arapahoe Avenue and Pennsylvania Avenue between 3 p.m. to 6:30 p.m. as attendees and advocacy groups arrive and between 8:15 p.m. to 9:15 p.m. when the debate adjourns. Regent Drive has been closed for the debate," said the spokesperson in a statement.

Debate ticket holders are expected to be onsite between 3 p.m. and 5 p.m.
